Perishable medical supplies often cannot be transported or delivered to remote areas, or they have a high percentage of spoilage. This is particularly problematic for cures of pandemic diseases such as Covid-19. Distribution and use of medical supplies can also be difficult to track, which makes it difficult to determine the need for additional medical supplies.
Embodiments of the invention solve the above-mentioned problems and other problems and provide a distinct advancement in the art of medical supply systems. More particularly, the invention provides a medical supply cart system that allows perishable medical supplies to be stored, transported, and delivered more effectively and efficiently.
An embodiment of the invention is a medical supply cart system broadly comprising a cart, a refrigeration device, a power system, and a communication module. The medical supply cart system is configured to provide mobile refrigeration for perishable medical supplies.
The cart includes an enclosure, a number of wheels, a drive motor, a number of lift points, a handle, a number of movable supports, and a number of controls. The enclosure includes a number of doors and may be substantially metal, plastic, composite material, wood, or any other suitable material. The doors allow access the refrigeration device , certain components of the power system, and in some embodiments the communication module, electrical wiring, and electronic components.
The wheels are rotatably connected to the enclosure and may be fixed-axle wheels, steerable wheels, or free-turning caster wheels. The drive motor is drivably connected to some of the wheels for propelling the cart. The drive motor may be powered by components of the power system. The lift points provide safe structure for lifting or hoisting the cart. The lift points may include lift rings, eye hooks, forklift tine channels, and the like.
The handle is positioned on one end of the cart and may be rigidly connected to the enclosure or may be pivotably or freely linked thereto. The handle may include controls or inputs for controlling the drive motor, for steering the cart, and/or for controlling various components of the medical cart.
The movable supports support the refrigeration device and certain components of the power system and may be slide-out or rotatable trays, drawers, or the like. The movable supports may be shiftable between a stored position and an access position to make various components more accessible.
The controls may be positioned near the respective component they control or monitor. For example, some of the controls may be positioned near the genset, other ones of the controls may be positioned near the batteries, while other ones of the controls may be positioned near the refrigeration device. The controls may include switches, buttons, dials, knobs, levers, display screens, touchscreens, mouses, keypads, gauges, indicator lights, speakers, and the like.
The refrigeration device may be configured to retain perishable medical supplies at a lowered temperature or lowered temperature range. In one embodiment, the refrigeration device may be configured to retain some of the perishable medical supplies in a first lowered temperature range and some of the perishable medical supplies in a second lowered temperature range different than the first lowered temperature range. In other embodiments, two refrigeration devices configured to retain perishable medical supplies at different lowered temperature ranges than each other may be used. The refrigeration device may be powered by the batteries or directly (i.e., not via the batteries) by the genset or the solar array (described below). The refrigeration device may also be powered directly or indirectly by external power via an external power connection, which may be an electrical outlet or other electrical interface.
The power system provides electrical power to the refrigeration device, the communication module, and other electrical and electronic components and may include a number of batteries, a genset, and a solar array.
The batteries store electrical energy for powering the refrigeration device. The batteries may be lithium, alkaline, or metal hydride batteries, super capacitors, or any other suitable electrical energy storage component. The batteries may also provide electrical power to the communication module, the drive motor, auxiliary lights, auxiliary power outlets, and the like. The batteries may also be charged by line voltage (via an electrical outlet or other electrical connection).
The genset may include an engine and generator and may be configured to charge the plurality of batteries. The genset may also provide electrical power directly to the refrigeration device (rather than first storing the electrical power in the plurality of batteries). The genset may also provide electrical power to the communication module, the drive motor, auxiliary lights, auxiliary power outlets, and the like. The genset may be configured to be run on gasoline, diesel fuel, natural gas, propane, or any other suitable fuel. To that end, a fuel tank may be mounted in, on, or near the enclosure to provide fuel to the genset.
The solar array may be mounted near a top of the enclosure and may include a stationary section and a movable section each including one or more solar panels. The stationary section may be rigidly connected to the enclosure, while the movable section may be shiftable between a stored position and a deployed position.
The communication module may generally allow components of the medical supply cart system to communicate with, transfer data to, and download software updates, programming, and direct commands from a remote server, cloud service, or other external system, mobile electronic devices, and the like. The communication module may include signal and/or data transmitting and receiving circuits, such as antennas, amplifiers, filters, mixers, oscillators, digital signal processors (DSPs), and the like.
The medical supply cart system 100 may also include other electrical and electronic components such as connecting wires, busses, converters, inverters, fuses, circuit breakers, and electrical outlets. The medical supply cart system 100 may also include other mechanical components such as valves, pumps, fuel regulators, lubricating systems, cooling systems, heating elements, radiators, and the like.
The above-described medical supply cart system provides several advantages. For example, the medical supply cart system may be used to refrigerate medical supplies such as vaccine dosages including Covid vaccine dosages to provide medical care in remote or mobile environment. The medical supply cart system includes several power options to accommodate local energy source availability. The medical supply cart system may also serve as a “hot spot” via the communication module. The communication module may also be used to transmit, to remote or external computing devices, data relating to the refrigeration device such as current temperature and number of medical supplies current stored or provided. The medical supply cart system may also be used as an electrical power station or even a mechanical power station via the engine of the genset.
